East meets West
You never really know what will turn up where. Walter Szeliga called me this morning to report a continuing Black-throated Gray Warbler and an American Redstart. The BT Gray is a western warbler, breeding in Pinyon/Juniper woodlands. Redstarts are an eastern species. They both managed to find the small patches of cottonwoods around Sale Lake in north Boulder. This tiny little pond and the riparian habitat that surrounds it have already produced several good vagrant warblers this spring including Northern Waterthrush and Black-and-white Warbler. I rode out after work this afternoon. The first thing I heard when I stopped to get off my bike was a WESTERN WOOD-PEWEE (#170). With Walter's help, I tracked down the AMERICAN REDSTART (#171) and the BLACK-THROATED GRAY WARBLER (#172). I visited Walden Ponds after Sale Lake, but didn't turn up anything of note there except stunning views of the continuing American Bittern.
On May 9, I birded along Boulder Creek before work. I picked up a singing WARBLING VIREO (#168) and an adult BROAD-WINGED HAWK (#169)
